ROBERT DEANE, OF BROOKLYN, NEW YORK.

HINGE-LOCK.

sPEoIrcArroN forming part of Letters Patent No. 485,613, ama November s, 1892. Application filed February 25, 1892. Serial No. 42237775. (No model.)

To all whom it may concern:

Be it known that I, ROBERT DEANE, a citizen of England, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Shutter-Locks; and I do hereby declare thefollowing to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a hinge-lock for shutters, blinds, or doors, the object being to produce a device simple and cheap in construction which may be applied to hinges ordinarily used and will serve to lock thetdoors, blinds, or shutters to which it is applied in a desired position of adjustment.

The invention comprises a tube provided with a central orifice adapted to slide over the knuckles or joints of the hinge, the walls of the tube being provided with slots symmetrically placed with reference to the walls of the tube. It also comprises a tube of this character provided with a plurality of slots symmetrically placed, one of which is adapted to embrace one member of the hinge and another the other member, whether it be a right or left hinge. It also comprises a tube provided with a series of slots, so as to secure the hinge in various positions of angular adjustment.

The invention will be more clearly understood by reference to the accompanying drawings, in connection with the following description.

Figure l represents a shutter, to which my hinge-lock is applied. Fig. 2 represents a perspective view of one form of my hingelock, showing a long slot and four auxiliary shorter slots for locking a shutter at different positions of adjustment. Fig. 3 shows a form of my device in which only two auxiliary slots are used.

The lock comprises a tubular structure, preferably made of hard metal--as iron, steel, brass, bronze, or nickel--from which it may be conveniently cast'. It may be cylindrical or polygonal in cross-section. The central opening should be of a diameter to fit over the joint or knuckles of the hinge to which it is to be applied. The device will be made of graded sizes to suit the dierent grades of hinges inuse. Parallel to the axis of the recess is a slot, as indicated at A, which slot is made of a greater length than the width of the strap B of the hinge. It is also provided with one or more additional slots C, which more additional slots the shutter can be locked at an intermediate angle. A flexible supportsuch as a chain or cord, as shown at E-is provided, by which the lock may be secured to the frame or wall adjacent to the hinge, so that it may always be ready for use. In the case of blinds or doors opening upon the inside of a room or building, the lock may be slipped upon the hinge when the shutter, door, or blind is closed. In such a case the strap and hook of the hinge lie superposed and the slot is brought into alignment with them and the locking device dropped over the joint. By providing the device with two or more auxiliary slots, in addition to the long slot, it is adapted to be used with either a right or left hand hinge, so that the same device may be used for any of thepurposes hereinbefore described.

I am aware that it has been proposed to lock a shutter-hinge by means of a flanged tube in which the iange is tangential to one side of the tube. In such a device a different design must be used with right and left hinges, requiring two different castings. With my device the same pattern will apply to either a right or left hand hinge, the arrangement of the slots described permitting such an application.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-` 1. A hinge-lock for shutters, blinds, or doors, comprising a tube adapted to slide over the hinge-joint and provided with a series of longitudinal slots in its walls, one of saidslots being symmetrically placed with reference to the walls of the tube, the otheil slots being at to admit of the use of the device on either 1o different angles to permit the hinge to be right or left hinges. looked at different angles of adjustment, and In testimony whereof Iax mysignature in ahflelzlzible support for securing the tube near presence of two Witnesses. te inge.

2. A hinge-lock comprising a. tube adapted ROBERT DEANE to slide ovel` the hinge-joint and provided with W'itnesses: a long slot to embrace both the strap and the NVILLIAM J. DRIVER, hook and symmetrically-placed shorter slots GRANT F. ADAMS.
